Abstract
In a retrospective, cohort study at 4 medical centers with high coronavirus disease 2019 vaccination rates, we evaluated breakthrough severe acute respiratory syndrome coronavirus 2 Delta variant infections in vaccinated healthcare workers. Few work-related secondary cases were identified. Breakthrough cases were largely due to unmasked social activities outside of work.
摘要
在四家 2019 年冠状病毒病（COVID-19）疫苗接种率较高的医疗机构进行的回顾性队列研究中，我们评估了已接种疫苗的医护人员中突破性的严重急性呼吸综合征冠状病毒 2 型（SARS-CoV-2）Delta 变异株感染情况。仅发现少数与工作相关的二级病例。突破性病例主要是由于工作之外未戴口罩的社交活动所致。
